Abstract
An information processing device includes a first processor, an information protection circuit, and a first communication path which connects between the information protection circuit and the first processor. The information protection circuit includes an interface circuit which connects the information protection circuit to the first communication path, a second processor, and a first memory which is inaccessible from the first processor but accessible from the second processor. When a command received from the first communication path is a command destined for the information protection circuit, the interface circuit passes the command to the second processor and the second processor executes a process related to information stored in the first memory in accordance with the command, but when the command received from the first communication path is not a command destined for the information protection circuit, the interface circuit does not pass the command to the second processor.
